Technical Specifications

The SSL0810T-221M-S features an inductance of 220μH (221 = 22 x 10^1). The 'M' indicates a tolerance of ±20% on the inductance value. Saturation current (Isat) and RMS current (Irms) are important parameters to consider. Refer to the datasheet for specific Isat and Irms values, which determine the inductor's ability to handle high current levels without significant performance degradation. The operating temperature range typically spans from -40°C to +125°C. The 'S' suffix most likely refers to a specific termination or packaging style, commonly tape and reel for automated assembly. The shielded construction uses a ferrite core to encase the inductor coil, effectively containing the magnetic field and minimizing EMI.

This inductor is commonly used in buck converters, boost converters, and SEPIC converters. In a buck converter, the inductor stores energy when the switch is on and releases it to the output when the switch is off, maintaining a stable and regulated output voltage. Its low EMI characteristics make it suitable for applications where electromagnetic compatibility is critical, such as in medical devices, automotive electronics, and aerospace equipment. Additionally, it can be used for filtering noise in power lines and signal lines.
